Standard Deduction
A fixed dollar amount that reduces your taxable income, available to all taxpayers who don't itemize.
What You Need to Know
The standard deduction is the IRS's way of giving everyone a baseline tax break. It reduces your taxable income automatically without needing receipts or documentation.
2025 Standard Deduction Amounts:
- Single: $14,600
- Married Filing Jointly: $29,200
- Head of Household: $21,900
- Age 65+: Add $1,950 (single) or $1,550 (married)
How It Works: If you earn $60,000 and take the standard deduction:
- Taxable income: $60,000 - $14,600 = $45,400
- You only pay tax on $45,400
Standard vs. Itemized: You can either take the standard deduction OR itemize (claim specific expenses like mortgage interest, charitable donations, medical expenses). You pick whichever is higher.
Most People Take Standard: Since the Tax Cuts and Jobs Act (2017) doubled the standard deduction, 90% of taxpayers now use it instead of itemizing.
When to Itemize: Only if your deductible expenses exceed the standard deduction:
- Mortgage interest on a $400,000+ loan
- $15,000+ in charitable donations
- Major medical expenses (>7.5% of income)
- High state/local taxes (capped at $10,000)
Example:
- Mortgage interest: $12,000
- Charity: $3,000
- Medical: $2,000
- Total: $17,000 → Itemize ($2,400 more than standard)
Pro Tip: If you're close, bunch deductions into alternate years (double charity in one year) to maximize benefits.
